188/4 Electronic Commerce Group

E-Business and E-Commerce include, besides other influencing domains, rapid changes to economic and social processes. For this reason, the E-Commerce group pursues taking an encompassing view at such processes reaching from analyzing enterprises and their respective processes to evaluating the entire market, as well as is active in creating ideas and solutions for meeting the demands of the respective stakeholders.

Overall, the E-Commerce group performs research and creates solutions in the Business-2-Business (B2B) and Business-2-Consumer (B2C) domains. In the B2B domain, the group focuses on (i) business (process) modeling and definition and consequently the specification and implementation of e-business systems while considering and contributing to semantic web research and service-oriented architectures, (ii) ontology engineering and information integration, (iii) "Web Science" focusing on network analysis and content as well as text mining. In the B2C domain, the E-Commerce group performs research targeting (i) visual interaction paradigms as well as (ii) mobile applications. Thereby, our group focuses especially on the development and application of our research in the area of e-tourism and its mobile applications.

Parts of the EC group are working on systems based research, namely on virtualized HPC systems, massive-scale data analytics and energy efficient ultra-scale distributed systems. Our goal thereby is to develop speculative methodologies and techniques to allocate resources in an energy efficient way, but at the same time meet requirements of the end users, like the certain latency of the applications. Our approaches are evaluated quantitatively on different scales by simulations, benchmarks or on experimental clusters. We strive to develop generic methods and methodologies but we let our research be inspired by a set of real world applications from different domains like life science (e.g., DNA sequencing) or social media (e.g., Facebook size data centers).

"Mine Your Own Business: Evidence-based BPM using Process Mining"

Guest talk by Wil van der Aalst
Turning Event Data Into Valuable Insights on Performance and Compliance
Friday, 11 April 2014, 11.00-12.30, EI 9

Recently, process mining emerged as a new scientific discipline on the interface between process models and event data. Whereas conventional Business Process Management (BPM) approaches are mostly model-driven with little consideration for event data, the increasing availability of high-quality data enables management decisions based on “evidence” rather than PowerPoints or Visio diagrams. Process mining can be used to (better) configure BPM systems and check compliance. Moreover, the high-quality event logs of BPM systems allow for advanced forms of process mining such as prediction, recommendation, and trend analysis. The challenge is to turn torrents of event data ("Big Data") into valuable insights related to performance and compliance. The results can be used to identify and understand bottlenecks, inefficiencies, deviations, and risks. Process mining helps organizations to "mine their own business": they are enabled to discover, monitor and improve real processes by extracting knowledge from event logs. In his talk, prof. Wil van der Aalst will provide an overview of this exciting field that will become more and more important for BPM.

Short biography:
Prof.dr.ir. Wil van der Aalst is a full professor of Information Systems at the Technische Universiteit Eindhoven (TU/e). He is also the Academic Supervisor of the International Laboratory of Process-Aware Information Systems of the National Research University, Higher School of Economics in Moscow. Moreover, since 2003 he has a part-time appointment at Queensland University of Technology (QUT). His research interests include workflow management, process mining, Petri nets, business process management, process modeling, and process analysis. Many of his papers are highly cited (he has an H-index of more than 107 according to Google Scholar, making him the European computer scientist with the highest H-index) and his ideas have influenced researchers, software developers, and standardization committees working on process support. In 2012, he received the degree of doctor honoris causa from Hasselt University. In 2013, he was appointed as Distinguished University Professor of TU/e. He is also a member of the Royal Holland Society of Sciences and Humanities (Koninklijke Hollandsche Maatschappij der Wetenschappen) and the Academy of Europe (Academia Europaea).

Project "Personalized representation of travel information to speed up the booking decision process"

In this project we study information needs of people that are interested in group tours as well as interactions between them. Compared to other travel related products, customers require more heterogeneous and detailed information when booking a group tour; the decision making process usually takes longer.

In our study we analyze user-generated content from the Web platform TourRadar.com. On this platform, group tours all over the world can be compared and booked. Furthermore, users are given the opportunity to engage with co-travelers in so-called meets before the tour starts. In those meets typically tour related questions are discussed. After the tour reviews can be published on the platform. A review may contain free text as well as five-star ratings for a number of categories such as value for money, guide and transportation. From both meets and reviews we extract topics that are relevant to the users with the help of text mining approaches, topic models and machine learning techniques. Furthermore, we apply social network analysis to study the user community of the platform and their dynamics.

The results of our analyses will be used to enhance the information content on the platform in order to facilitate the decision making process of the customers.

Project "EIT ICT Lab Austria"

The EC group has - together with Eutema and i2c - launched a new project "EIT ICT Lab Austria". Its aim is to prepare an Austrian participation in the ICTLabs of the European Institute of Technology (EIT).

The EIT ICTLabs belong to one of the first Knowledge and Innovation Communities (KICs) of the EIT and are an initiative of the European Union. Since 2010, the ICTLabs brings together researchers, scientists and companies to implement IT innovations for economic growth and quality of life in Europe. The partners of the ICT Labs encompass leading academic institutions, top universities and industrial heavyweights in Europe. This project is designed to prepare an application for membership in the ICT Labs so that Austrian organizations may have access to the European wide network of the ICTLabs.

IEEE TMC Event: "Validated Learning / Split Tests for Web Applications"

For start-ups related to web applications, the topic of validated learning & split tests is very important (see e.g. the book "The Lean Startup"). This event will be in German language and will report about our practical experience in applying the idea of split tests to TechnoWeb. If you are interested, you are invited to participate in the event. The participation is free of charge. A registration at http://doodle.com/aeu34xbrch5s922u is required.

Original Invitation (in German):
Liebe IEEE-Mitglieder (deren Societies dem IEEE Technology Management Council zugeordnet sind),

Das IEEE Technology Management Council Chapter Central Europe lädt Sie im Rahmen unserer Social Media Serie wieder zu einer spannenden Praxis-Veranstaltung ein:
Diesmal zum Thema
"Validated Learning / Split Tests bei Web-Applikationen"
Impulsvortrag von Andreas Oertl.

Datum: Mittwoch 27.11.2013
Zeit: 17:30-19:00, anschließend gemeinsames Abendessen, wer Lust hat.
Ort: TU-Wien, Favoritenstraße 9-11, 1040 Wien, 4. Stock, SEM 188/2,

Wer das Buch "The Lean Startup" gelesen hat, weiß wie wichtig es ist, so früh wie möglich Feedback von den Usern zu bekommen, ob ein neu eingeführtes Tool oder auch nur ein neues Feature in einem bestehen Tool wirklich das bewirkt, was angedacht ist.

Im Rahmen vom TechnoWeb Projekt haben wir erste Erfahrungen mit Split-Testing (oder A/B Testing) gemacht. Dabei wird nur einem zufällig ausgewählten Teil der User ein neues Feature zur Verfügung gestellt, um messen zu können, ob es die gewünschte Wirkung hat. Gar nicht so einfach wie wir dachten. Andreas Oertl ist bereit über die Erfahrungen zu berichten (TechnoWeb ist nur das Anwendungsbeispiel – das Thema selbst hat aber nichts mit TechnoWeb zu tun). Solche Messungen sollten sinnvollerweise statistisch signifikant sein, um Entscheidungen daraus ableiten zu können.
Bitte um Info, wenn auch wer von Euch Ebenfalls Erfahrungen hat und bereit ist darüber zu berichten – dann können wir das in die Agenda einplanen

Die Teilnahme ist kostenlos. Eine Anmeldung via Doodle ist jedoch erforderlich: http://doodle.com/aeu34xbrch5s922u

Beste Grüße,
Andreas Oertl und Michael Heiss
